Making a placeholder menu item
A lot of people like to make a nice menu in their websites, but do not want the top level to work as part of that menu, just the drop down areas. Kind of like having the top level of the menu just be titles. There are two ways to achieve this and both are very easy.
Now you need to change a piece of the code:
var nav_titles = ['Page 1','Page 2','Page 3','Page 4'];
You will need to change the Page 1, Page 2, Page 3 and Page 4 in the code to the name of the pages you want to not work in the navigation. If you have less than 4 pages, just delete the extras, if you have more, add them.
